Questions on Homebrewing Stack Exchange are expected to relate to homebrewing within the scope defined in the FAQ. Consider editing the question or leaving comments for improvement if you believe the question can be reworded to fit within the scope. Read more about closed questions here.
A rollback is when a question has been edited by another user, and you wish to "roll back" to a previous version.
It's covered in this meta question - http://meta.stackoverflow.com/questions/56287/how-can-i-get-the-cleanup-badge
